Kubectl apply -f ingress.yaml

error: resource mapping not found for name: "your-ingress" namespace: "your-namespace" from "ingress.yaml": no matches for kind "Ingress" in version "networking.k8s.io/v1beta1" ensure CRDs are installed first

Solution: change networking.k8s.io/v1beta1 for networking.k8s.io/v1 or your K8s version: kubectl api-resources | grep networking.k8s.io
